GEORGE A. FAIR, OF LOS ANGELES, CALIFORNIA.

Application filed May 26, 1914. Serial No. 841,108.

To all :whom it may concern.

Be it known that I, GEoRon A. FAIR, citizen of the United States, residing at Los Angeles, in the county of Los Angeles and lated, the construction being such that direct drafts are preventedr A further object of the invention is the provision of a window so constructed that outer and inner sashes may be used to inclose a dead air space between them, and

the inner pair of sashes may be used for controlling the inlet of fresh air and the outlet of vitiated air without losing the dead air space between the sashes.

A. further object of the invention is the provision of a window of very simple construction in which ventilation may be readily controlled and in which dead air space is provided between the outer and inner sashes so that the window may be used under a large variety of climatic conditions so as to either secure a maximum of fresh air, as in summer, or secure the inlet of as small an amount of fresh air as required and the independent outlet of the vitiated air.

' Other objects will appear in the course of the following description.

panying drawings wherein:

Figure 1 is a front elevation of my improved ventilating window construction. Fig. 2 is a vertical section through the windowon the line 22 of Fig. 1. Fig. 3 is a cross section on the line 33 of Fig. 1.'

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

Referring tothe drawings, 43 designates the window frame within which is pivoted a sash frame 44, this sash frame being pivoted in any suitablemanner as by means of the pivot pins 45 so that the entire sash may be opened out. As illustrated in Fig. 3, the

Specification of Letters Patent.

My invention is illustrated in the accom- SASH-CONTROLLED VENTILATING WINDOW 0R DOOR.

Patented Apr. 20, 1915.

. 5 outside wall of each vertical bar ofithe sash frame is rectangular in shape and is hinged at 46 to the inside wall 47. The two sections of the sash frame are heldin closed position by means of bolts 48 or other suitable devices.

The'window illustrated is provided with a pair of inner sashes designated 50 and 51 respectively, and a pair of outer sashes designated 52 and 53 respectively. These sashes are mounted to slide between the inner walls 47 of the vertical bars of the window frame in any suitable manner and have the usual sash cords 54; passing over pulleys 55. Preferably one sash of each pair of sashes counter-balances the other sash of the same pair and thus when the lower sash of one pair is forced upward the upper sash of the same pair will lower, and vice versa.

The sill ofthe sash frame is designated 56 and forms the top of a transversely extending hollow casing 57 which extends entirely across the window and forms the lower bar thereof. This lower hollow bar or casing 57 at its outer portion extends above the sill 56 so as to form a ventilation box 58. The outside face of the hollow bar 57 is formed with an air inlet opening 59 and an inner wall 60 deflects the air entering through this opening into the ventilation box 58. The inner wall of the ventilation box is formed by a screen 61. It will be seen that the lower sash 51 of the inner pair of sashes when closed rests upon the sill 56 but that when the lower sash 51 is raised sufliciently, the upper sash will lower so as to rest upon the upper wall of the ventilation box 58; It will likewise be seen that in the lowered position the sash 51 when resting upon the sill 56 will close the opening across which the screen 61 is disposed but that when the lower sash is raised air will be admitted from the ventilation box 58 into the room. The lintel ofthe sash frame is formed by a hollow casing 62 having a portion 63 at its upper end which overhangs the sill 56. The front of the casing 62 is formed below the overhanging portion 63 with the opening 64 screened by wire gauze 65. The outer face of the casing has an opening 66 for the admission of fresh air and fresh air is directed upward into the upper portion of the casing which forms a ventilator box by. means of the deflector plate 67.

It will be noted that when the inner sashes are in their closed position the upper sash 50 will engage with the under wall of the overhanging portion 68 and will close the opening 64;, but that when this upper sash is lowered this opening will be unclosed and fresh air will be admitted into the room. It will be seen then thatby raising the lower sash the upper sash will be lowered, and thus air will be admitted through the screened opening 61 and 'the hot air willpass out through the upper openingl6ior fresh air may enter through this upper opening, just as circumstances dictate.

The rear sashes operate between the upper wall of the ventilation box 58 andthejlower wall of the box or casing 62 and preferably, one sash counterbalances the other. Ordinarily during the winter months, the outer pair of sashes are not opened and the inner pair of sashes only opened to an extent which, will inclose the openings 61 and 64.

V Thus'the dead airspace 68 betweenthe ,inner the room, at right angles to the plane of the,

windows I preferably provide a deflector plate designated 69 and illustrated in Fig. 2. This deflector plate is disposed vina slot 70 formed in the sill 56 and at its upper end is flanged as at 71 so that it cannot'drop' down too far through .thisslot .70. It is also provided witha ring or other form ofhandle 72 whereby it may be pulled up. The lower extremity of the plate 69 is deflected as at "('3 so that when the plate is pulled up to its full extent it may be tipped and will hold I inplace without-the necessity of using any fastening device forthe purpose.

Parting strips Tel, are of course, disposed between the front and'rear pairs of sashes, thus holding these front and rear parts of sashes separated. Preferably the window frame is reinforced by outer reinforcing members designated 75 forming channels 7 6 within which a shade may be disposed while the inner portion of the window casing is reinforced by the reinforcing members 77 (see 'Fig. 3). providing a channel within which a screen of wire gauze may slide This form of window is particularly appli. cable for use in Pullman cars which in winter require a dead air space betweentheouter and inner sashes'and in which there'is a great deficiency in proper ventilation. It

is, however, obvious that the invention is not necessarily limited to its usein' Pullman cars but may be applied to the windows of "houses and other buildings, with equally good results. It will, of course, be under- ;stood thatthe window is shown deeper in proportion than it actually willbe, in order to show the parts distinctlyg 7 While this form of the invention .hasbeen shown as applied to windows "I wish dis-' tinctly understood that itmight also :be an. 7

plied to doors. Of course, I

do not wish to be limited to; the details of construction shown inthegfig- ,ures, although I regard certain details as preferable, it'being obvious that many changes might be "made in the invention without departing from the spirit thereof,

andthat my invention may be applied to many different forms of Windows, and may also be applied to doors as well as windows,

Would constitute in that case the frame of "the window and that either sashes or panels could be used in place ofthe ordin'aryjwindow sashes. Q Inasmuch as the it being obvious that the frame of the door construction would be practical for doors as well as a hinged window, such as illustrated in the drawings, I have not felt it necessary to illustrate the application of my invention to, a door, and r I wish it understood that by the terms 1 sashes, I not ,only'intend to include window sashes but also panels, such as would f be found in a door construction.
